[gmx-users] energy group exclusion

[David L. Bostick]

Does the option

energygrp_excl = group1 group2

in the mdp file force mdrun to exclude the calculation of nonbonded force
on group1 due to group2 (and vice versa)?  It would make sense that it
does, since force = -grad(energy) but these may be calculated separately by mdrun.
However, I just want to be sure.

Thanks,
David
